PLS HELP ME NOW ITS PYTHAGOREAN THEOREM

rusak2 [61]

Answer:

a =2.2

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2

where a and b are the legs and c is the hypotenuse

a^2+2^2 = 3^2

a^2 +4 = 9

a^2 = 9-4

a^2 = 5

Taking the square root of each side

sqrt(a^2) = sqrt(5)

a = sqrt(5)

a=2.236067977

To the nearest tenth

a =2.2

A student buys a guitar that is on sale for 15% off the regular price of $200. He also must pay an 8% sales tax. What is his tot

EastWind [94]

Answer:

option c

Step-by-step explanation:

a guitar 15% off means that the cost is now 85%

$100percent---200dollars\\85percent---x\:dollars\\\\x=\frac{200*85}{100}\\\\x=2*85\\\\x=170$

now the 8% of 170 is

$100\:percent---170\:dollars\\\\8\:percent---x\:dollars$

$x=\frac{8*170}{100}\\\\x=\frac{8*17}{10}\\\\x=13.6$

so the total cost is

170+13.6

183.6
